SPECIFICATION forming part f Letters Patent No. 421,7 59, dated. February 18, 180.

Application filed May 10, 1889. Serial No. 310,240. (No model.)

To all whom it may concern/.-

Be it known that I, CHARLES A. POPE, of

' Cleveland, inthe county of Cuyahoga and l burner-cone.7

State of Ohio, have invented certain new and useful Improvements in Vapor-Burner Cones; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the- In the accompanying drawings, Figure l isV an elevation, in section through the center of the burner. Figs. 2 and 3 are respectively top and bottom plans of the burner-cone.

A represents the commingling-tube, the same discharging into commingling-chamber B. This chamber is covered by means of disk C, the latter`constituting the so-called The disk is provided with a series of narrow concentric slitsc for the discharge of gas from chamber B hence instead of jets of llame projecting laterally, as with ordinary cones, sheets of iiame are projected upwardly, so as to directly impin ge the vessel or article being heated.

The burner shown is of the Argand variety; but this is not material. The cone when made of cast metal is provided with the depending annular ribs C C2 and radial ribs C3,y all cast The top wall is thin and the slits c integral. are cut in a lathe, ribs C3 holding in place the concentric rings between the slits. The cone may be struck up of sheet metal, in which case slits c would be punched out, and in place of ribs C2 the slits would be segmental,

leaving solid radial sections corresponding with ribs C2.

There is no material difference in the Working of. the cast or sheet iron cone. It is quite expensive to provide dies, punches, '&c., suitable for manufacturing the wrought-metal cones; but having such tools provided the wrought-metal cones can be made cheaper than the cast-metal cones.

Vhat I claim i's- The combination, with a commingling-l chamber open at the top, of a removable disk having downwardly-projecting ribs overlapping the edge of the commingling-chamber and provided with a series of concentric slits, substantially as set forth.

In testimony whereof I sign this specification, in the presence'of two Witnesses, this 10th day of April, 1889.
